I have an Eglu classic and run - not cheap, but they are very well made and you do see them second hand sometimes. They are very good for just a couple of hens.

I also have a larger coop from Green Frog, which is more basic, but still sturdy and has all they need. I already had a walk-in run for it to go in and they are good value if you want a bigger size in housing.

Both are very easy to clean and I have had no red mites in either. If you did, you could take either apart, clean them thoroughly and get them dry and back together the same day. I wouldn't go back to wooden housing now
